...you may consider changing loop-AES name to something more generic
then ;-)

anyway, I can't help thinking that you're in the process of recreating
the international kernel patch....
 
ps: ...are you aware of any data corruption problems with loop-AES in
combination with XFS on SMP boxes under high IO load? if I get the time,
I can try to recreate the issue with 2.4.18; it was present w/ 2.4.16
the last time I checked, and it affected both, loop-AES and patch-int...

btw, that's a known problem (see this mailing lists archives for more
details); when it was detected it was too late, thus left so, since it
would have broken existing encrypted volumes...
